Not yet sure if AudiophileMusings will make it this year or not, but The Bristol Hifi Show (formerly the Sound and Vision Show) takes place 22nd to 24th February.
Its the biggest commercial show in the UK and therefore attracts a large number of visitors and exhibitors.
Interesting to note that Linn are attending with the Selekt product - a departure from their usual low profile marketing:
